Abstract

A rotary sliding discal valve of gas flow regulation was designed, and its working principle was studied.The working process's dynamic mathematical model of the gas flow regulation system was established.The characteristics of negative regulation, frequency and variation parameters were analyzed, and the influencing factors of system gain and time-constant were obtained.Also, simulation was carried out to verify the theoretical derived results.Both of theoretical analysis and simulation present that the designed gas flow regulation system based on the rotary sliding discal valve can be effective on gas flow regulation, and it is also a non-minimum phase system.The conclusion provides a reference for improvement of gas flow regulation system.
